Some of the best moments have been when I barely survived.I lost my ship when I claimed one during the story line. Almost all of my materials were on the ship that I lost, and the ship I'd claimed was completely broken and non functioning, and to top it all off, the planet was undergoing a permanent radiation storm that could sap my hazard protection in about 30 seconds or so. That was the one and only time that I've actually felt some tension in the game and it was absolutely delicious. Wish there were more situations like that sprinkled throughout the galaxy and story.
That's why I find my current frozen planet so much fun to play. Without any upgrades to the suit, I can survive about 1:30+ in normal weather, and only 30+ sec during storm. It's very exciting.
